Brazilian and US American children were compared for differences in tolerance and punishment expectancy. We hypothesized that participants would be less tolerant and more punishing of moral than conventional violations; tolerance and punishment expectancy would relate with age; Brazilians would tolerate less and expect more punishment than US Americans; and social domain would moderate effects of age and nationality. The sample had 129 matched children from Brazil and the USA. Moral/conventional-violation vignettes were used. Mixed-model GLMs suggested that children were less (...) tolerant and more punishing of moral than social-conventional violations. Age effects were significant for tolerance. Brazilians scored lower on tolerance and higher on punishment expectancy than US Americans; they also differentiated less between violation domains than US Americans. These and other results suggest that Brazilians tolerate less but expect more punishment for violations than US Americans. Discussion is based on cultural and socio-historical differences between the two nations. (shrink)

We provide a complete classification of the possible cofinal structures of the families of precompact (totally bounded) sets in general metric spaces, and compact sets in general complete metric spaces. Using this classification, we classify the cofinal structure of local bases in the groups C(X, R) of continuous real-valued functions on complete metric spaces X, with respect to the compact-open topology.

La problemática adaptativa constituye un tema central para la teoría evolutiva. Uno de los principales cuestionamientos está dado por aquellos procesos que tradicionalmente se han considerado como adaptativos y que a la luz de la evidencia actual deben ser redefinidos. El estudio de la adaptación en el caso del parasitismo reviste especial importancia por sus aspectos epidemiológicos, ecológicos y evolutivos, además de su impacto en medicina evolutiva. El objetivo del presente trabajo es hacer un estudio de casos en cestodes con (...) el propósito de contrastar el grado de aplicación de la definición de adaptación propuesta por Dressino y discutir su viabilidad, limitaciones y alcances para el fenómeno parasitario. Se analizan numerosas definiciones y conceptos de adaptación y se advierte que muchas de ellas no cuentan con los requerimientos formales necesarios para su corroboración empírica. En base al análisis de casos de cestodes y teniendo en cuenta los conceptos de “interrelación de eslabones del ciclo biológico” y “potencialidad del fenómeno parasitario”, se propondrá el concepto de “concatenación de adaptaciones”. En razón de las particularidades adaptativas observadas en parásitos y de la inviabilidad de las definiciones de adaptación aplicadas a estos grupos, este nuevo concepto supone una multiplicidad de adaptaciones que se enlazan unas con otras y que la modificación de cualquiera de ellas tiene profundas consecuencias en las restantes.Adaptative issues constitute a central topic in evolutionary theory. One of the main questions concerns the processes that have traditionally been considered as adaptative and that should be redefined in the light of current evidence. The study of the adaptation in the case of parasitism was especially important for its epidemiological, ecological and evolutionary aspects, besides its impact on evolutionary medicine. The purpose of this work is a study of cases in cestodes in order to contrast the degree of application of the definition of adaptation proposed by Dressino and to discuss its feasibility, limitations and reaches for the phenomenon of parasites. A large number of definitions and concepts of adaptation is analyzed and it is observed that many of them do not fulfill the necessary formal requirements for their empiric corroboration. Based on the analysis of cases of cestodes and keeping in mind the concept of “interrelationship of links in the biological cycle” and “potential of the parasitic phenomenon”, we proposed the concept of “concatenation of adaptations”. Due to the adaptative particularities observed in parasites and the non feasibility of the definitions of adaptation applied to these groups, this new concept assumes that there is a multiplicity of adaptations that are linked to each other and that the modification of any one of them has profound consequences on the remaining adaptations.

The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary (...) characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

The present study aimed to analyze the stability of the memory of a stressful event (medical examination within a hospital setting) over time in young people (age range 12 to 21, Mage = 15.11 years old, SD = 3.047) with mild or moderate intellectual disability (IQ = 54.32, SD = 13.47). The results show a stability of the memory of what happened an hour and a week after the event in relation to the people involved, the apparatus used, and the (...) parts of the body explored. No interaction effects were found between the stability of memory over time and the level of intellectual disability. The level of disability (mild or moderate) only affected the description of the doctor who performed the exploration and the explored parts of the body, showing better results for people with mild disability. In addition, the results highlight the relationship between memory and IQ, especially verbal IQ. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

This paper deals with an (otherwise classical) two-(non-interacting) particle system immersed in a common stochastic zero-point radiation field. The treatment is an extension of the one-particle case for which it has been shown that the quantum properties of the particle emerge from its interaction with the background field under stationary and ergodic conditions. In the present case we show that non-classical correlations—describable only in terms of entanglement—arise between the (nearby) particles whenever both of them resonate to a common frequency of (...) the field. For identical particles the entanglement becomes maximum and must be described by totally (anti)symmetric states. (shrink)

The scientific study of consciousness emerged as an organized field of research only a few decades ago. As empirical results have begun to enhance our understanding of consciousness, it is important to find out whether other factors, such as funding for consciousness research and status of consciousness scientists, provide a suitable environment for the field to grow and develop sustainably. We conducted an online survey on people’s views regarding various aspects of the scientific study of consciousness as a field of (...) research. 249 participants completed the survey, among which 80% were in academia, and around 40% were experts in consciousness research. Topics covered include the progress made by the field, funding for consciousness research, job opportunities for consciousness researchers, and the scientific rigor of the work done by researchers in the field. The majority of respondents (78%) indicated that scientific research on consciousness has been making progress. However, most participants perceived obtaining funding and getting a job in the field of consciousness research as more difficult than in other subfields of neuroscience. Overall, work done in consciousness research was perceived to be less rigorous than other neuroscience subfields, but this perceived lack of rigor was not related to the perceived difficulty in finding jobs and obtaining funding. Lastly, we found that, overall, the global workspace theory was perceived to be the most promising (around 28%), while most non-expert researchers (around 22% of non-experts) found the integrated information theory (IIT) most promising. We believe the survey results provide an interesting picture of current opinions from scientists and researchers about the progresses made and the challenges faced by consciousness research as an independent field. They will inspire collective reflection on the future directions regarding funding and job opportunities for the field. (shrink)

The human brain’s ongoing activity is characterized by intrinsic networks of coherent fluctuations, measured for example with correlated functional magnetic resonance imaging signals. So far, however, the brain processes underlying this ongoing blood oxygenation level dependent (BOLD) signal orchestration and their direct relevance for human behavior are not sufficiently understood. In this study, we address the question of whether and how ongoing BOLD activity within intrinsic occipital networks impacts on conscious visual perception. To this end, backwardly masked targets were presented (...) in participants’ left visual field only, leaving the ipsi-lateral occipital areas entirely free from direct effects of task throughout the experiment. Signal time courses of ipsi-lateral BOLD fluctuations in visual areas V1 and V2 were then used as proxies for the ongoing contra-lateral BOLD activity within the bilateral networks. Magnitude and phase of these fluctuations were compared in trials with and without conscious visual perception, operationalized by means of subjective confidence ratings. Our results show that ipsilateral BOLD magnitudes in V1 were significantly higher at times of peak response when the target was perceived consciously. A significant difference between conscious and non-conscious perception with regard to the pre-target phase of an intrinsic-frequency regime suggests that ongoing V1 fluctuations exert a decisive impact on the access to consciousness already before stimulation. Both effects were absent in V2. These results thus support the notion that ongoing slow BOLD activity within intrinsic networks covering V1 represents localized processes that modulate the degree of readiness for the emergence of visual consciousness.

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

A paradigm shift in public health and medicine has broadened the field from a singular focus on the ill effects of negative states and psychopathology to an expanded view that examines protective psychological assets that may promote improved physical health and longevity. We summarize recent evidence of the link between psychological well-being and physical health, with particular attention to outcomes of mortality and chronic disease incidence and progression. Within this evolving discipline there remain controversies and lessons to be learned. We (...) discuss measurement-related challenges, concerns about the quality of the evidence, and other shortcomings in the field, along with a brief discussion of hypothesized biobehavioral mechanisms involved. Finally, we suggest next steps to move the field forward. (shrink)

There are two aims of this paper: (1) to explore the affective dimensions of moral shock and how it relates to normative marginalization of those furthest from dominant society, but also, more specifically; (2) to articulate the trans experience of constantly being under moral attack because the dominant “world” normatively defines you out of existence. Toward these ends, I build on Katie Stockdale’s recent work on moral shock, arguing that moral shock needs to be contextualized to “worlds” of sense to (...) understand how marginalized people affectively experience shocking events. My focus is the trans experience of moral shock due to the way trans people are positioned outside of dominant society, creating the conditions to experience cyclical, chronic shock. These affective conditions point to a collective responsibility to ease the affective stress that the most marginalized experience. (shrink)

This reply addresses observations of Drs. Larsen, Kruse, and Sweeny, and Scherer in their reviews of our published work on the link between positive psychological assets and outcomes of physical health. Inspired by Obama’s Precision Medicine Initiative we argue that the interplay between the emotion spectrum and health is likely a complex and heterogeneous amalgam of known and yet unidentified elements melding at the individual level. When exploring the emotion–health link, researchers are challenged to grapple with complex system models by (...) considering multiple hierarchies of information that span individual-level factors, genetic blueprints, and cultural and environmental context. Research is needed to more fully elucidate the mechanism through which emotion influences health, with careful consideration of differences across race/ethnicity, culture, and context. (shrink)

En la Universidad Médica “Carlos J. Finlay”, se realiza una intervención educativa con el objetivo de valorar la concepción y aplicación de un programa para un curso de preparación de metodólogos en correspondencia con sus funciones en condiciones de universalización de las Ciencias Médicas de Camagüey, en el periodo de septiembre de 2005 a junio de 2007. Se emplean diferentes métodos investigativos: los teóricos, así como la técnica de discusión grupal, permitió diseñar el programa del curso para la preparación de (...) metodólogos en condiciones de universalización y los empíricos, la obtención de algunos datos de interés acerca de los metodólogos que reciben el curso y sus valoraciones en relación con el mismo. Se constata que la preparación pedagógica y experiencia en el desempeño es insuficiente para asumir el rol de metodólogo y valoran de muy importantes los contenidos desarrollados, los métodos y formas organizativas concebidas, por lo que se concluye que el programa del curso cumple con las expectativas del metodólogo al estar diseñado teniendo en cuenta las funciones que estos desempeñan y sus necesidades sentidas A study was carried out about the intervention in education developed to increase teacher's methodological preparation under their new functions due to the fresh conditions of learning within the community applied to medicine training and education in Camagüey. It was carried out in the period of September 2005 to June 2007. Different research methods were used: the theoretical ones and the technique for group discussion help to design the course syllabus and the assessment for those teachers that received the course. It was verified that the methodological preparation and performance experience are insufficient to play their role; but they value as very important the contents, the methods and the organization of the course. The authors conclude that the course meets the expectations of training, because it was designed keeping in mind the teachers' functions and their necessities. (shrink)

There is a curious phenomenon where people from marginalized populations are taken to be arrogant when they show no signs of superiority. In effect, their actions are misconstrued, and their attitudes are rendered unintelligible. Given that arrogance is standardly taken to be a flaw in one’s moral character, understanding such misattributions should give us insight into the affective marginalization many people face. This talk aims to give a thorough exploration of arrogance under oppression. I argue that arrogance is a kind (...) of self-preoccupation that involves projecting one’s values, goals, and concerns onto others as if they were objective values, goals, and concerns. When the affectively marginalized communicate their self-respect through things like protest, people mistake that self-respect as self-preoccupation given how the affectively marginalized are constructed. Furthermore, given how affective marginalization not only inhibits how the marginalized are understood by others, but inhibits their own affective lives, I argue that taking up an arrogant attitude is not always morally vicious, but can be a beautiful form of political resistance but all things considered good.

Philosophers of race and other writers in the Black and Latinx intellectual traditions have remarked on what it is like to live under “the racial gaze,” to be shaped and limited by the way whites perceive us. However, little work has been spent developing how the racial gaze functions in whites’, and other racially privileged people’s, moral psychology. I argue in this paper that there is a morally objectionable way of perceiving people of color. This claim builds on an insight (...) from Iris Murdoch that our perception can be morally evaluable and extends it to issues of race. I articulate how racial stereotypes and misvaluing distort one’s perception of people of color and that these distortions are organizing around a dominant conception for race that plays an important role in the oppression of people of color. I believe understanding racist perception lays a foundation for understanding the moral dimensions of interpersonal (as opposed to structural) racism. (shrink)

With increased visibility of trans people comes increased philosophical interest in gendered language. This chapter aims to look at the research on gendered language in analytic philosophy of language so far, which has focused on two concerns: (1) determining how to define gender terms like ‘man’ and ‘woman’ such that they are trans inclusive and (2) if, or to what extent, we should use gendered language at all. We argue that the literature has focused too heavily on how gendered language (...) can harm trans people, and has not considered how trans people use gendered language to create meaning and joy for ourselves. Pulling from the literature in sociolinguistics, we look at examples of how trans people use language to make their lives better by gaining recognition, playing with gendered language, finding joy in gendered language, and taking control of definitional power, concluding that debates about gendered language need to consider not only how such language harms trans people but also how trans people use it for our own liberation.

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation (...) and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

Research on adolescent-to-parent violence associates specific psychosocial characteristics with adolescents who assault their parents, whether they are within or outside the juvenile justice system, or whether these characteristics are shared by other adolescents convicted of other crimes. The aim of this paper is to compare three groups of adolescents. Those who have been sentenced for APV are compared with adolescents who have committed other crimes, and with a group who have not been involved in the justice system. The sample used (...) consists of 148 male participants between the ages of 14 and 21. A comparison is made regarding type of self-reported behavior, frequency of drug use, academic performance, exposure to violence, self-concept, and parents’ conflict resolution tactics. The results obtained indicate that adolescents with judicial measures, regardless of the crime committed, differ from those who have not been in trouble with the justice system in terms of them having suffered violence in the street, the frequency with which they use drugs and in their academic achievement. Likewise, adolescents convicted of APV differ from the other two groups in the frequency with which they are victims of violence at home, in that their mothers use the tactic of asking somebody else for help as a way of solving marital conflicts, and in having a more negative family self-concept. The results are discussed highlighting the importance of taking into account whether a sample is judicial, clinical, or community, and the specific APV behaviors which are measured. (shrink)
